摘要
采用XPS测试方法,研究了电磁场模拟微重力环境下高锂含量Al 5%Li合金锂在凝固组织中的分布情况。通过与未施加电磁场的试验样品中锂在合金组织中分布的比较,结果表明:在电磁场模拟微重力的环境下,施加的电磁力可有效的抑制高锂含量导致的锂在凝固组织中所产生的偏析。
The distribution of higher lithium content of Al-5wt%Li alloy, which prepared by using the technique of electro-magnetic simulating gravity-segregation, has been investigated by means of XPS.By the comparison of lithium distribution in structure with that no applied electromagnetic field, it shows that the separation of lithium caused by the increase of Lithium content in Al-Li alloys can be restrained effectively due to the application of the electromagnetic force under the circumstance of electro-magnetic simulating gravity-segregation.
